Abstract

The present invention uses a set address for distinguishing a set instead of using a separate modem address between the sending modem and the receiving modem for communication between devices having a power line modem. This invention allows the set and powerline modem to communicate with each other to replace the set's address with the address of the modem and to communicate with the modem connected to the set of other bodies using the modem address replaced with the set's address.

Therefore, since the set and the modem do not use different addresses, it is possible to solve the limitation of having to have a tool for setting an address for each modem and the hassle of setting the address of the modem.

Description

How to set the address of power line modem {ADDRESS SETTING UP METHODE FOR CARRIER CURRENT TRANSCEIVER}

The present invention relates to an address setting method of a power line modem, and more particularly, to an address setting method of a power line modem in which an address of a set of a device main body is replaced with an address of a modem.

In general, in order to perform communication between devices by connecting home appliances to a network, a modem for processing data modulation and demodulation is installed, and the modem is connected to an external device through a communication medium and uses a mutually agreed communication protocol. Will be transmitted and received.

In recent years, a so-called power line communication has been put into practical use as a means of eliminating the enormous cost burden caused by the construction of transmission lines.

In order to perform power line communication, a power line modem is installed in a home appliance, and the power line modem is in charge of connecting communication between devices that are separated from each other through a power line.

1 is a view for explaining an address setting method of a power line modem according to the prior art, which is an example of performing communication between power line modems connected to set 1 and set 2. FIG.

As shown, power line modems 20A and 20B are connected to sets 10A and 10B of each device body, and modem 1 20A and modem 2 20B are connected through a network. The set 1 (10A) and the modem 1 (20A) is connected to each other by a communication line to communicate with each other. Thus, the set 2 (10B) and the modem 2 (20B) is also connected by a communication line to communicate with each other.

Conventionally, in order for Modem 1 (20A) and Modem 2 (20B) to communicate with each other, the other party's modem address must be known in order to recognize the other side modem, and in order for Set 1 (10A) and Set 2 (10B) to communicate with each other, the other side set is required. You must know the other party's set address in order to recognize it. Therefore, it is necessary to individually set the addresses in advance in the set 1 (10A), the set 2 (10B), the modem 1 (20A), and the modem 2 (20B). However, in order to set an address in a set and a modem, it is necessary to consider a case where a plurality of modems are installed in a set. Therefore, a protocol having a complicated algorithm is used and expensive network management is required.

An object of the present invention is to set the address of a power line modem so that the trouble of having to set an address for each modem can be eliminated by replacing the set address with the modem address using a protocol for setting the address between the set of the main body and the modem. In providing a method.

10A, 10B: Set of device body 20A, 20B: Power line modem

An object of the present invention as described above is a method of setting an address of a power line modem connected to a set of device bodies, the method comprising: communicating the set and the power line modem with each other to replace an address of the set with an address of the modem; And communicating with a modem connected to a set of other bodies using the modem address replaced by the set of addresses by the above steps.

The address replacement step includes the steps of connecting the modem to the set, requesting transmission of a set address from the modem to the set, sending a preset set address from the set to the modem, And setting the set address received by the modem as its own modem address.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

2 is a view for explaining an address setting method of a power line modem according to the present invention, and will be described with the same reference numerals for the existing components.

As shown, power line modems 20A and 20B are connected to sets 10A and 10B of each device body, and modem 1 20A and modem 2 20B are connected through a network. The set 1 (10A) and the modem 1 (20A) is connected to each other by a communication line to communicate with each other. Likewise, the set 2 (10B) and the modem 2 (20B) is connected by a communication line to communicate with each other.

In the present invention, the set 1 (10A) and the modem 1 (20A) of the device body replace the set address with the modem address using the protocol, and the set 2 (10B) and the modem 2 (20B) of the other device body also use the protocol. After the process of replacing the set address with the modem address in advance, communication between the set 1 (10A) and the set 2 (10B) is performed.

Modem 1 (20A) and Modem 2 (20B) recognize the other party's modem with the modem address replaced by the set address, and Set 1 (10A) and Set 2 (10B) have the other party's set address assigned to it. Recognize. Therefore, when the set address is set in the set 1 (10A) and the set 2 (10B), the modem connected to the set may replace the set address with the modem address through mutual communication.

This address replacement process will be described in detail with reference to FIG. 3, and descriptions will be given for set 1 and modem 1, and descriptions for set 2 and modem 2 will be omitted.

Referring to FIG. 3, a protocol for address replacement between modem 1 (20A) and set 1 (10A) is prepared in advance (S100), and modem 1 (20A) is connected to set 1 (10A) using this protocol. Request (S200).

When the mutual connection is made by the connection request, modem 1 20A requests transmission of the set address to set 1 10A (S300).

Subsequently, the set 1 10A transmits its set address to the modem 1 20A according to the request for transmitting the set address (S400).

Subsequently, the modem 1 20A sets and replaces the set address received from the set 1 10A with its own modem address (S500).

Subsequently, the modem 20A performs communication between modems using the modem address replaced with the set address of the set 1 10A (S600).

In the case of using the protocol between the set and the modem as described above, a given data format is used. That is, the data format consists of a header, a set type, a send address, a receive address, a mode, data, and a tail. Here, the header uses "02H" to signal the start of the data format, the tail uses "03H" to signal the end of the data format, and the mode (MODE) indicates the type of data and requests for address transmission, for example. Use "10H" for and "20H" for the response of the completion of reception of the address. The receiving address and the sending address inform the data receiving side and the transmitting side address, respectively, " 01H " and " 02H " The SET TYPE is used to distinguish the type of the set, and "30H" represents an air conditioner and "F7H" represents a server (set).

Looking at the process of address replacement between Set 1 and Modem 1 using the data format,

1) When requesting address transmission from modem 1 to set 1

02H-F7H-00H-00H-10H-DATA-03H

2) When sending set address from set 1 to modem 1

02H-30H-01H-00H-20H-DATA-03H

3) In case of modem 1 having set address and send address received from set 1 as modem address

30H-01H

4) Set the set address of set 2 as the modem address of modem 2 through 1), 2), 3) between modem 1 and set 2.

5) Modem 1 and Modem 2 communicate with each other by using modem address replaced by set address.

As described above, the present invention provides a restriction on the address setting of the modem and the limitation that the set and the modem should have a tool for setting an address for each modem by replacing the address of the set with the address of the modem without using different addresses. Eliminate the hassle
